RGA Assemblies
RGA Assemblies include braking resistors completely assembled and mounted in a
NEMA 1 enclosure. A listing of available RGA assemblies is provided in Table A-2. The
minimum resistance “Minimum Ohms” shown in the table is the minimum resistor value
that can be connected to the control without causing damage to the internal dynamic
brake transistor for E, ER and MR controls.

minimum resistance “Minimum Ohms” shown in the table is the minimum resistor value
that can be connected to the control without causing damage to the internal dynamic
brake transistor for E, ER and MR controls.
RGA assemblies can also be used with EO and MO controls in combination with an RTA
assembly when more than 4000 watts of brake capacity is needed. In this case, the
minimum resistance of the RGA assembly must be equal to or greater than the minimum
resistance specified for the RTA assembly. Refer to Section 3 “Optional Dynamic Brake
Hardware” for wiring diagram.
